TYPEW'BITING MACHINE,

Application fi1ec1 December 11,1925. Serial No. 74,668.

This invention relates to work-sheet handling devices for typewriting machines, and is shown as applied to an Underwood twinplaten machine.

In some systems of typewriting bookkeeping, it is sometimes desired to fill out a bill-sheet which is inserted around one of the platens, and then to copy the total of the bill upon a ledger-sheet on the other platen, said total being manifolded upon atally-strip which is permanently left in the machine.

In trying to feed a tally-strip which is wider than the ledger, a difiiculty arises, because the tally-strip cannot be fed independently of the ledger as heretofore. It has been customary to provide a tally-strip behind a ledger-sheet for the purpose of'copy ing a portion of the data typed upon the ledger, and in such cases the tally-strip is made narrower than the ledger, and by eliminating the center feed-rolls it is posvsible to line space the same by means of a positively driven rewind spool. The ledgersheet is line spaced by means of the regular feed-rolls engaging the borders of the ledger, the feed-rolls being, of course, arranged to clear the tally-strip. Since it is desired to use a wide tally-strip in this invention, it will be clear that such a receiving spool could not be used in connection with the feed-rolls, because the ratio of feed on the spool is variable, whereas the ratio of feed on the platen is constant, and, ofcourse, the strip would either sag or break, depending on the size of the receiving spool.

In order to remedy this condition it is proposed to eliminate the receiving spool, and to feed the tally-strip, together with the ledgen-sheet, by means'of the feed ro11s, the tally-strip being permitted to recoil itself into a roll of suitable size, which is torn off against a knife at convenient intervals.

In this invention novel means are provided for handling such work, the means being in the nature of anattachment for ma chines provided with two platens. According to certain features of this invention the tally-strip is inserted, together with a strip of carbon in front thereof, around the righthand platen to which it is fed from a supply-spool at the rearof the machine, means being provided, at the delivery side of the plateinforguiding the strip upwardly to a point where it is automatically refolded upon a supporting shelf. The tally-strip is held on the platen by means of paperfingers, and the feed-rolls of the machine are released in order that the ledger-sheet may be positioned to the printing point with the aid of a front paper table, upon which the ledger-sheet is held in printing position by means of a paper-finger or resilient clamp.

The bill-sheet is inserted around the leftplaten is moved to present the ledgensheet to the printing point, so that the total and possibly some identification mark may be typed on the tally-strip. The platen is then line-spaced to position the tally-strip for the first line of typing and the feed-rolls are released to withdraw both the bill and the ledger-sheets.

One of the features of this invent-ion relates to novel means for feeding and rewinding the tally-strip, the usual rewinding spool having been dispensed with, so as to permit the tearing off of portions of the tallystrip, as may be required from time to time. The tally-strip is guided against a plate at the delivery side of the platen and the strip is permitted to recoil itself into a roll of suitable length. It is customary to run the length of the strips to about one foot, which usually assembles all the daily totals of the bills sent to the various customers.

' Another feature of this invention relates to means for facilitating the tearing off of the tally-strip. To this end, there is provided alrnife secured to a front table atthe,

top edge thereof. Said knife extends the full. width of the tally-strip and is adjush ably mounted on the. front table to permit the handling of ledger-sheets of various widths. i

In this particular embodiment of the invention it is desired that the identification numeral appearing in front of each item,

side of the ledger, upon which margin the identification.numeral may be typed.

Other features and advantages will here inafter appear.

This invention is applied to an Underwood twin-platen machine, such as disclosed in the patent to T. J. Coo, 1,539,384, dated May 26, 1925; Said machine includesa pair.

of platens and 11 mounted on a platenaxle 12, which is supportedby end plates13 and 14 of a'platenframe which is borne by "a carriage, not shown. The platen 10 iscon:

nect edby means .of atubing 15 to a fingerwheel'16,1and may be rotated independently of the other platen. The platen 11 tis fast to theaXle'12 by means of ascrewfl'l, the

axle carrying fast thereto another fingerwh eel18. By means of this arrangement it is possible to rotate either, pla-ten.independently of the other.

According to the 'method of handling the workinthis invention, a tally-strip 19, hav,'

ing a'super'posed strip. of carbon 20, is'draWn down fronrzi'supply-spool 21 mounted on af shaft22, the ends of both strips being inserted at the rear of the platen around the sa ne, and up ,in' front 'thereof. The tallystrip is passed under paper-fingers 23, bear ng on the platen, and is then led up over a table 24gwhich serves as a backing to prevent the'curling of the tally-strip, Owing to the naturaltendency of the paper to curl itself,

once having: been'woundjon a spool for some tin e;-thejsam'e is permitted to be recurled upon a supporting shelf 25. The paperfingers are provided with pressure rollers 26, and maybe swung into and out of position in the regular manner. are slidably mounted on a shaft 27 which serves as a brace forthe end plates 13 and 14 of the platen frame;

Previously to inserting the tally-strip, the usual feed-rolls 28 are released, the tallystrip' being held'in place by means of the paper-fingers 23. e The feed-rolls are r0 tatably mounted upon shafts 29, extending the full length of bothplatens, so that the feed-rolls may be simultaneouslyoperated for both platens. v A ledgersheet,30 is' 'then inserted at the realof the platen u'nder'the same and is led Said paper-fingers over a front table 81 to be laterally posi-h tioned, by meanso'f side gages 32, and also positioned to the printing line by gaging the same against front scales 83, whereupon a pressure finger 34: is swung into operated position, as shown in Figure l, to hold the ledger-sheet while a bill sheet 35 is inserted on a shaft 40, the latter being fast to endplates-tl whichare in turn secured to the plates 13 and llof the platen frame by be removed from the bracketswithout necessitating the withdrawing of s upporting' screws44e, 7' f in order to facilitate the "easy replacement ofthe supplyspool 2l',"therefis provided a pair of plates 45 piyotally mounted on the shaft 40, the'pla'tes being tied together by means of'a tube l6 and a bracea'od 47. The tube' 46' is secured to the plates 45 by means of screws 48 and carries, fast thereto, the table24r. 'By means of this arrangeinent, the supply-spool is easily replaced by rotating the shaft 22, whiclris provided with a finger-piece 49, thereby presenting fiat- V tened portions 50 toslots 51 in the plates 41,

'In order tofifacilitate-the tearing oil of portions "of the "tally-strip, there is provided a knife 52 fast to one of the sections of theftable 31 by means of rivets 52-3; The

otherend of the knife is adjustably secured to, the other section of the table by means of a screw 54 passingfthrough an elongated slot 55 in said table andscre'wing into a tapped hole in the, knife. a Referring more particularly to Figure-5,

in which a longitudinal sectional view o'fthe supply-spool 1s shown, it will be" noted that means of screws-42. The cros's bar is provlded with slots 43 so that the same may the same is provided with removable heads 57 designed to enter a tube 56 around which the tally-strip is wound. By means of this arrangement, the heads are withdrawn from the used spool and are reinserted into the tube of a fresh spool when needed.

Variations may be resorted to. within the scope of the invention, and portions of the improvements may be used without others.
